Subject: [PATCH 0/2] Set PCNoC clk always-on, with or without interconnect

The PCNoC clock needs to always have some sort of a vote hanging onto
it, so long as the AP is alive. Some platforms guarantee that through
the interconnect driver, while others (that register the PCNoC clk
with the clock framework) don't, which results in a big kaboom and
force reboot when trying to suspend that clock.

Solve the issue for the latter group.
